Fadavi was quoted Tuesday by the semi-official Fars news agency as saying the size of the U.S. carriers makes them an "easy target."

Fadavi also says the Guard navy has already carried out an exercise targeting a mock-up of an American warship.

Last month, an Iranian newspaper reported that Iran's military was building a simple replica of the USS Nimitz in a shipyard in the southern port of Bandar Abbas in order to be used in future military exercises.
